In 1965, the ABC decided not to purchase the twelve-episode Doctor Who story 'The Daleks' Master Plan' (1965 - 1966), deeming it inappropriate for broadcast in the show's pre-7pm timeslot (a problem that also plagued numerous John Pertwee-era and Tom Baker-era stories).
Furthermore, the story was not novelised as part of Target Books' series of Doctor Who novelisations until 1989, when John Peel produced a two-volume novelisation. (Volume one novelised 'Mission to the Unknown', a one-episode introduction to 'The Daleks' Master Plan' notable for the complete absence of the primary cast, and episodes one to six of 'The Daleks' Master Plan'; volume two, published under the title The Mutation of Time, novelised episodes seven to twelve of 'The Daleks' Master Plan'.)
In 1980, therefore, Australian fans had no means of experiencing 'The Daleks' Master Plan' and no likelihood of seeing it novelised. Rosemary Howe's novelisation was designed as a means of allowing Australian fans to experience the story. Published over three issues of Zerinza, it was the first novelisation of this story. It has subsequently been reprinted several times, sold overseas, and republished in various places online.
